Abstract

In a first aspect of the present invention, a lighting device includes a substrate that includes a pair of electrodes as a first electrode and a second electrode, groups each including a same number of light-emitting elements that are electrically connected to one another in series in each group and that are arranged between the first electrode and the second electrode, a first light-transmitting member including a first phosphor and covering at least one light-emitting element and a second light-transmitting member including a second phosphor and covering at least one light-emitting element that is uncovered by the first light-transmitting member, the first phosphor in the first light-transmitting member and the second phosphor in the second light-transmitting member being configured to be excited to emit light with emission spectrum different from each other, and the first light-transmitting member being enclosed by the second light-transmitting member.
